, To all whom it may concern Be it known. that I, AUGUST 'Dmma cit1-.zen of the United States, residing at 7 Meridian, in the county, ofLauderdale and State of Mississippi, have invented certain.

new and useful Improvements in Bending- Machines, of which the followingis a specification. V I v An object ofthis invention iQ the provision ofa bending machine specially de signed for straightening or re-shapingsuch parts of motor vehicles as the axle, controlling rod and-the beamsof the frame.

Another object is the provision of a device of this character embodyinga frame on I which the operating screws are slidable longitudinally andprovided with means for locking the screws in adjusted-position.

Another objectis the provision of a novel type of clamp detachablyconnected with the end of. each operating screw and adapted to securethe machine in operative position upon the object tobe bent.

' With these and other ObJGCtS in view, the invention consists in thenovel construction,

arrangement and combination ofparts as will be hereinafter specificallydescribed, claimed and illustrated in the accompanying drawings, inwhich,

Figure 1 represents a side elevation of the machine. applied; to use,Fig. 2 represents a top plan view thereof, partly in section, Fig. 3represents a transverse sectional view through the machine, partlybroken away, and, Fig.4 represents a detail sectional view, partlybrokenflaway, of one of the clamp retaining heads.

Referring to the drawing indetail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numerals5 indicate a pair of side rails connected at their extremities bytransverse beams 6 and constitutin the frame of the bending machine. Aplura ity of rectilinear hollow housings 7 are provided adja cent theopposite ends with transverse open-.

ings slidably receiving the side rails 5'of the frame andhaving athreaded opening in one end wall of each housing to receive a set screw8 whereby the housings are secured in adjusted position on the frame.Each of the housings 7 is formed with circular openings disposed atright angles to the openings receiving the side rails 5 and rotatablyreceiving a screw 9 having suitsptcification of Letters Patent.

,able-aperturesf 10 in one end to receive an -operatin'g hand;le 11.

The frame carries three housings :7 and a cular openings or recessesrotatably receiv- '9 intermediate the collars 12 and 13. The

heads are provided with transverse recesses through the walls ofwhichpivot pins 18 are secured. i 4

ing the saidunthreaded portion of the screw Within each of the" housings7 a block 19 7 having a central threaded recess receiving the screw 9 islocated. The inner ends .of a

pair of clamping jaws 20 are pivotally secured onthe ends of the pins18. of each head and said ,jaws are provided intermediate their lengthwith openings receiving a bolt 21 having a suitable nut 22 whereby thejaws may be. drawn into clamping engagement with an object to be bent.The adjacent-faces of the free extremities of the jaws 20 are providedwith a plurality of recesses 23 of suitable shape to engage about theobject to be bent.

In operation, when it is desired to .straighten an axle of the usualI-beam type, as illustrated. at 24 in Fig. 3, the jaws 20 of each pairarearranged to receive the horizontal portion of the axle 24 in therecesses 23 and the nuts 22 operated to rigidly "clampthe jaws inoperative position. The center or end screws 9 are operated by thehandles 11 until the object is straightened or assumes the propercurvature. By separating the members 14 and 15 of the center head, it isclearly apparent that the ends of the operating screw 9 may be engagedagainst an axle spindle and the outer pairs of clamping jaws 20 engagedwith the spokes ofa wheel to remove the latter, or to straighten it, asdesired. 7

What I claim is:

1 A device of the character described.

blocks posi- 2 ings therethrough, operating screws siderail's and havingscrew threaded opentioned through said threaded openings, means forsecuring said housings in adjusted-position, and clamping jaws pivotallyconnectd with the ends of said screws. A 2. A device of the characterdescribed comprising a frame i'n'elt'ndinglongitudinal side rails,hollow housings adjustable longitudinally on'said side rails, means forsecuring"'said housings in adjusted position, blocks positioned Withinsaid-housings and having= screw" threaded ope'nings' there osithrough,.operating screws positioned v through said threaded openings, two-part15' heads detachably secured tofone end of. said screws, jaws pivotallysecured tosaid heads and having a plurality of recesses in their,

free extremities, and means for securing sald aws in operative p0s1t1onon an ob]ect. 2o
